Yu-Ping Wu 8112c95a06 Enable VBOOT_VBNV_FLASH for SOC_INTEL_BRASWELL 
To deprecate VBOOT_VBNV_CMOS [1], replace VBOOT_VBNV_CMOS with
VBOOT_VBNV_FLASH for boards using SOC_INTEL_BRASWELL.

Currently BOOT_DEVICE_SPI_FLASH_NO_EARLY_WRITES is selected for
CPU_INTEL_HASWELL, SOC_INTEL_BRASWELL and others (see [2]). However,
there seems to be no particular reason on those platforms. We've dropped
the config for haswell. Now do the same for SOC_INTEL_BRASWELL, so that
VBOOT_VBNV_FLASH can be enabled.

VBOOT_VBNV_FLASH is enabled for the following boards:

- facebook/fbg1701: A 0x2000 RW_NVRAM region is allocated, with the
  FW_MAIN_A(CBFS) size reduced by 0x2000.
- google/cyan, intel/strago: Repurpose RW_UNUSED as RW_NVRAM.

[2] commit 6c2568f4f5
    ("drivers/spi: Add BOOT_DEVICE_SPI_FLASH_NO_EARLY_WRITES config")

BUG=b:235293589
TEST=./util/abuild/abuild -t FACEBOOK_FBG1701 -a (with VBOOT selected)
TEST=./util/abuild/abuild -x -t GOOGLE_CYAN -a
